question is in the title. i seem to remember reading that advancing cam gears too much with toda b's will eat valves. any truth to this?

 

Advance it too much and valves will touch the pistons= goodbye valves

It's always a good idea, especially with aftermarket cams with more lift, to check piston to valve clearance and how much the cams can safely be advanced/retarded without getting into trouble.

 

tnx for the response. actualy i put cam gears on my jdm b18cr with stock cams. i set it at +3 (6degrees)on the intake cam, am i still on the safe side?

 

Set it back to 0,0 and get on a dyno

Exactly.

How did you decide on the 3° setting? Without a dyno, you have no way of determining what effect the adjustments are having.

 

i did dyno it. the guy put my cam gears at +4 in, -4 ex. don't really trust the guy who did the adjustments, thats why i'm asking this question. +4 is around 8degrees advanced, im afraid of valve to piston contact with this setting
